Working out at home is delightfully simple—especially when a single button press makes your session a bit smarter. The SportsHero treadmills with 13% automatic incline (RunningPad Pro & WALKR Pro) instantly level up your walk or run: more calorie burn, stronger muscles, and less joint stress. In this post you’ll see why 13% is such a powerful difference and how to start today.
Why incline training works
When you add incline:
-
You activate more and larger muscle groups—glutes, hamstrings, and calves work harder.
-
Your heart rate rises faster at the same speed, increasing metabolic load.
-
You shift impact from “hits” (running) to driving force (climbing)—kinder to knees and hips.
-
You raise energy cost per minute without necessarily going faster.
In short: more training stimulus without more speed. Ideal indoors or when you want to move while working.
Why 13% is especially effective
An incline of 10–15% is often called the indoor “sweet spot”:
-
Steep enough to meaningfully boost calorie burn and muscle tension.
-
Still controllable for technique and safety—even in longer sessions.
-
Highly versatile: from easy fat-burn walks to punchy interval blocks.
With 13% you get the room to progress progressively: micro-steps (e.g., 4% → 7% → 10% → 13%) plus short, powerful hill repeats without dangerously high speeds.
What does 13% deliver, concretely?
More calories per minute
At the same speed, walking with a strong incline can demand up to 2× more calories than walking at 0%. That’s because you:
-
recruit larger muscle groups,
-
hit a higher heart-rate zone,
-
and often “hang” less on the belt (better posture).
Muscle building & shape
-
Glutes/hamstrings: more hip extension → stronger posterior chain.
-
Calves: continuous push against the slope → stronger lower legs.
-
Core & posture: slight lean from the ankles, long torso → natural “uphill” technique.
Happier joints
You draw intensity primarily from incline, not speed. This reduces peak loads on knees and lower back—great if you’re impact-sensitive.
Use 13% smartly: 4 proven formats
Use RPE (perceived effort, 1–10) or your heart-rate zones. Fat burning often sits around 60–75% of max HR.
1) Fat-burn blocks (gentle build-up)
-
Duration: 30–40 min
-
Speed: comfortable (you can still talk)
-
Plan:
-
5 min warm-up – 0–3%
-
5 min – 6%
-
5 min – 9%
-
5 min – 11%
-
5 min – 13%
-
5–10 min cool-down – 0–3%
-
-
Goal: steady fat burning, practice good posture.
2) Hill repeats (strength & cardio)
-
Duration: 25–35 min
-
Speed: moderate/strong (RPE 6–7 uphill)
-
Plan (×6):
-
2 min at 13%
-
2 min at 3% recovery
-
-
Start with 4 repeats and build to 6–8.
3) Desk-walking (productive movement) – WALKR Pro
-
Duration: 20–50 min, spread through your day
-
Speed: 2.5–4.5 km/h (workable pace)
-
Incline: 3–7% (light challenge)
-
Tip: every 5–10 min add +2% for 1–2 min, then return.
4) Progressive climb – RunningPad Pro
-
Duration: 20–30 min
-
Speed: easy to strong (RPE 4–6)
-
Incline: every 2 min +2% until you hit 13%, then hold 3–5 min.
-
Goal: mental focus and strength endurance.
Technique: stay strong and safe at 13%
-
Posture: slight forward lean from the ankles; chest open, shoulders down.
-
Cadence: a bit shorter and rhythmic. Avoid big, swinging steps.
-
Gaze: neutral (don’t look at your feet).
-
Rails: holding for balance is fine, but aim for hands-free as soon as you can.
-
Breathing: deep and rhythmic; can you still speak in phrases? You’re in a good endurance zone.
-
Build-up & cool-down: raise incline in 1–2% steps; lower gently before stepping off.
13% in your routine: practical planning
-
2–3× per week: hill session (repeats or progressive)
-
1–3× per week: steady-state fat burn with rising incline
-
Daily: 10–30 min light incline (3–7%) while working or watching TV → free extra steps
Tip: treat incline and speed as independent dials. Knees talking? Lower speed and keep the incline stimulus.
FAQ
Is 13% too much for beginners?
Not if you build up gradually. Start at 3–5%, extend the blocks, and add 1–2% per week until 10–13% feels comfortable.
Is walking on incline more effective than flat running?
For fat burn and muscle activation, often yes—especially around 13%. Plus, the impact is lower than fast running.
Can I walk at 13% while working?
Pick a low speed and a light incline (3–7%). Save 10–13% for short stimuli or separate sessions.
